what i have atm is an input which takes a simple String of Text, converts it to binary then hides it in a picture using Pillow.then i have a second program which takes the picture and finds the hidden binary but i don't know how to convert the binary back to text. I'm just experimenting with putting the binary from the first part direct into this because the part of hiding and finding it on a picture is on another computer which i don't have access to atm and not on my personal laptop.thanks

In your opinion, what is a binary number? Because there is no such thing. You can have a string written in binary format that represents a number. And there are numbers, which computers internally store in binary format--but since all numbers (and even characters) are stored in binary on a computer, how does calling something a binary number distinguish it from all other numbers?

Were you provided with this program, or did you make it yourself? Either way, I want to know where you/they learned about this. Also, are you sure that you're outputting to binary and not just encoding something into some made-up codec with a script?
